Background: Rust-bellied Piranhas are vicious creatures, evolved to have razor teeth and a mean disposition. Their primary hunting tactic is to immediately rip to shreds anything that comes in contact with the surface of the water, usually birds. This instinct also drives them to rip apart boats, though.
